Specification forming part of Letters Patent No. 19S, 729 dated'becember 25, 1877 application filed To all whom it may concern:

' Be itknown that 1, MARK HOUSE, of

Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in 'MachinesforJointing Sections .of Pipe; and-I do hereby declarethe following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it pertains to thislsp ecification: I n

Myinvention relates to an improvedfmachinefor jointing sections of pipes made from sheet metal and. itconsists in thefollowing fied'and claimed.

In the drawings, Figure 1 is a planj view oi mydeyice; Fig.2, an inverted view there.

of; Fig. 3, an isometric view of the same.

in theform of Fig.4c is a yertical transverse section of the machine, Fig. 15 is adetached sectional view Ais a revolving table, carrying a revolv-[ ing table-holder, B. The table A'is turned,

thiiough the agencyof a pinion, A engaging Withgear-teeth upon the periphery or under side of the table A. In said table is made a central opening, A, for the accommodation of the pipe-sections to be Jointed "and the clamping device that holds the pip'e'during the operation of making the j oint. This clamping device 0 is made in two, three, four, or more sections, and these sections are adapted, by suitable mechanism, to gripe or release the inclosed pipe, as may be necessary. I have a simple and effective method of operating said clamp, which is by the use of a partially-rotating cam-ring, G moved by a handle, G or any suitable attachment. The operation of this'cam -ring 0 upon the sections of the clamp O is to simultaneously separate or unite them, and thus open or close said clamp, and gripe or release the inclosed pipe-section, as it is turned one way or the other.

The revolving tool-holder B, which is attached to and carried by the revolving table A, is adapted to carry one, two,'or more sets O ctober 29,1877.

ishing-dies, B constituting two sets of jointing-tools;

1 In theoperation of the machine the clamp J'is stationary, likewise, therefore, the pipesections held by it whilelthe table A and the jointing-tools are revolved'around said pipewhile operating upon it. On account of this peculiar operation it is necessary th'atthe tools while in action should be held to'their work, and for this purpose I providean abutment, D, against which'the armof any'operating-die shall rest. This abutment I make cally] depressed and removed, 'will act .to pretool-arm.

h v P vid d me ns whereby th v aha-tment D may beeith'er manually or automati. j

cally operated.

It willbe observed that the aue Arests and revolves upon a stationary tabletEl, which is supported by the legs E; To tthisls' tatinn ary'table I attach a sliding bar, F,"'.vvhich, y

when in one position, will operate to depress and release the abutment D, and when in another position will not operate at all upon said abutment. The bar F is moved through the agency of a bell-crank, F and this bellcrank is operated by any suitable treadle or handle, F A spring, F retains the bar F in its position to trip the abutment D at every revolution of the table A, and the treadle or handle 13 is employed when it is desired that the bar F should not operate. n

I do not limit myself to theconstruction of the yielding abutment D and the means for operatin g it, my invention being, broadly, to

any abutment the equivalent of the abutment D, and any suitable means whatever whereby said abutment may be automatically or manually removed when any jointing-tool shall have completed its function, so that said tool may alternating with eachother,

a spring-latch, beveled .n'pbn f its'rear portion, so as to yield, and allow any ,tool-arm' to pass over it in a backward dirc} tion', but which, unless ,manually ora'utomati;

lution of this die accomplishes the desired re-' sult, the bar F will be permitted automatically to trip the abutment D, which has thus far been holding the coaxing-die to its work, and

permit said coaxin g-die to be moved out of the way, and the finishing-die B brought into play. If, however, one revolution of the coaxing-die has not accomplished the desired result, the handle or treadle F is operated, and the bar-I thus prevented from tripping the abutment D, which thus continues its work of holding the coaxing-die to its work for another revolution. Thus it will be seen that any die may be caused to operate until it has done its work, when it can be automatically released.

Mymachine is so constructed that any length of pipe may be jointed by it. It is susceptible of operating in either a horizontal or vertical position, as may be desired,without the necessity of any material modification, excepting in the manner of its support. I WhatIclaim is 1. The revolving table A, carrying the Q tating tool-holder B, substantially as and for the purpose specified. H

' 2. The revolving table A and rotating toolholderB, in combination withthe clamp O, substantially as and for the purposes shown.

3. The revolving table A and abutment D, in combination with the arm or holder of a jointing-tool, substantially as and for the purpose shown; V

4. The yielding abutment D, substantially as and for the purpose shown.

5. The yielding abutment D, in combination with the sliding bar F, substantially as and for the-purposes specified. 5 j

6. In a machine for joining pipe-sections,the

combination, with the yielding. abutment, of

mechanism for operating it, substantially as described.

7 The combination, with the central stationary clamp, of the table surrounding it, and provided with gear-teeth upon its periphery or lower surface, whereby it may be revolved by a suitable pinion, substantially as described.

8. The combination, with the central clamp and the surrounding table, of the revolving tool-holder and suitable dies or tools for making a pipe-joint, substantially as described.

9. The combination, with the revolving table A and tool-holder B, of the yielding abutment D and sliding bar F, substantially as and for the purpose shown.

10. In a machine for jointing sections of pipe, the combination, with the revolving table and the sectional clamp, of the tool-holder, adapted to carry one or more sets of diesor tools, substantially as described.

11." The combination, with the revolving table, of the central clamp, composed of concentric sections, substantially as described.

v 12. The combination, with the revolving table and the central clamp, made in two or more sections, of the eccentric-ring and suitable mechanism for operating the same, substan; tially as described. p 1 V v 13. The. combination, with the'revolving table and the central sectional clamp, of the co:

centric-ring and the actuating-handle, substan tially as described.

14. The combination, with the revolving ta' ble and tool-holder,.of the yielding abutment and mechanism, as described, for operating the same, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of.

two subscribing witnesses.
